Ah red rainbow fish, thats what the seller told me, I added tetra, my bad. The size of my tank is 24 X 16 X 16 inches. Its a mid sized tank.They are not Tetras, they could well be young Red Rainbowfish (Glossolepis Incisa) and can potentially reach 6 inches (150mm), what size tank have you got them in?
That's a bit small for them length wise as they need space to swim.Ah red rainbow fish, thats what the seller told me, I added tetra, my bad. The size of my tank is 24 X 16 X 16 inches. Its a mid sized tank.
Agree, young red rainbows. They don't look like much for a long time and take an age to colour up. I had them with other rainbows when I was a kid and personally wouldn't go for a tank smaller than 4ft but preferably 5ft+ (ours were in a 6ft and they didnt make the tank look big). They are very chunky, deep bodied, active fish when mature. I would also want to keep them in harder water, they wont do great in soft acidic conditions.
